A light emitting device housing having a concave part is provided therein for housing a light emitting device. Side surfaces of the concave part are each configured to be a perpendicular surface that is substantially perpendicular to a bottom surface of the concave part, and other side surfaces are each configured to be an inclined surface for reflecting light from the light emitting device toward above the light emitting device.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A light emitting device housing including a concave part that receives a light emitting device, comprising: a single silicon substrate comprising the concave part formed therein that has a bottom surface that a plurality of side surfaces surround, said side surfaces of the single silicon substrate including: first and second side surfaces that are substantially perpendicular to the bottom surface of the concave part, said first side surface being disposed on a first side of said light emitting device while said second side surface is disposed on a second side of said light emitting device, and wherein said first side surface faces toward said second side surface and is spaced a distance from said second side surface, and a plurality of inclined side surfaces that are disposed at ends of the first and second side surfaces so as to extend between said first and second side surfaces, said inclined side surfaces extending upwardly from a lower end intersecting said bottom surface and serving to upwardly reflect light from the light emitting device, the plurality of inclined surfaces comprising first and second pairs of inclined surfaces, and the first pair of inclined surfaces being adjacent each other and the second pair of inclined surfaces being adjacent each other, wherein via electrodes are formed through the bottom surface of the concave part, and the via electrodes are electrically connected to the light emitting device.
2. The light emitting device housing according to claim 1 , wherein the light emitting device has a rectangle shape, and the light emitting device is disposed such that each of the long sides thereof faces an adjacent one of the first and second side surfaces the light emitting device housing.
3. The light emitting device housing according to claim 1 , wherein the light emitting device has a rectangle shape, and the light emitting device is disposed such that each of the long sides thereof faces an adjacent one of the first and second side surfaces of the light emitting device housing.
4. The light emitting device housing according to claim 1 , wherein the light emitting device has a quadrangular shape, and the light emitting device is disposed such that each of the long sides thereof faces an adjacent one of the first and second side surfaces of the light emitting device housing.
5. The light emitting device housing according to claim 1 , wherein the light emitting device has a quadrangular shape, and the light emitting device is disposed such that each of the long sides thereof faces an adjacent one of the first and second side surfaces of the light emitting device housing.
6. The light emitting device housing according to claim 1 , wherein the first and second side surfaces are surfaces corresponding to <010 >planes of the single silicon substrate and the inclined side surfaces are surfaces corresponding to planes of the single silicon substrate.
7.
